I've just moved into a place where the internet stops working at quite regular intervals throughout the day. I used the program "network stumbler" and i see the signal is nearly always there except every 15mins or so there is a very short time where the signal dissapears for about a second and then comes back. I've noticed that once this blip in the signal happens, even though the signal is telling me the internet is there, I have to use the "repair" feature by right clicking the wireless icon in the task bar other wise it doesn't want to work. I find myself doing this about 10 times a day and is quite annoying.

Like I said, I have just moved into this place and have not really checked the hardware setup in the landlords office downstairs but I have noticed there is a linksys router which is set to automatic and the wireless access point which is currently on connected with 3/5 bars of signal but usually doesnt drop any lower. Please excuse my relative lack of knowledge here, but I'm hoping someone can help.

Also, the landlord is going through the same thing as me and he's not a computer wiz either but he says that ever since this other guys moved in with his wireless x-box machine he's been having problems with his internet, sounds unlikely to me but thought I'd throw that out there.

1. interference from other wifi networks. Try changing the wireless channel used on the router and on your (and your landlords) computers. You'll need to go into the router set-up to change the router one, and you can change the computers in hardware settings (device manager -> network adapter) normally or in any wireless software you have.

2. the router may have a timeout on it, i.e. if unused for more than a certain period it drops the wireless to save power. Make sure any timeouts in the router setup for this are set to zero.

3. power supply in the house. I've seen some routers where the power-supply gets a spike every so often and this causes them to drop the wireless. Don't ask why, it's bizarre but this can happen.
